How to make a bayonet bend, a return bend, using a steel pipe bender. Step-by-step tutorial. Learn how to make a return bend on a single steel tube using a hydraulic pipe bender. In this video, the desired height is 10 cm, and the tube is 15/21 or 1/2 inch black steel. The minimum bend radius for 1/2 inch tubing is 12.5 cm on my pipe bender. (This dimension is measured between the center of the bend wheel and the center of the roller.) For a return bend height greater than 13 cm, a 45° angle is usually used. _____________ Tools needed to make the bayonet bend ___________________ Steel pipe bender Screen square Paper Measuring tape ________________ Chapters in this video _____________________________ Here is the step-by-step tutorial. 0:10 Set up the pipe bender in 1/2 bend mode. 0:27 Draw two lines 10 cm apart, mark the beginning of the bend. 0:57 From this line, use your measuring tape as a compass to draw the minimum angle. 1:13 Measure the bend angle using a bevel gauge. 1:22 Mark the bend axis on the tube. 1:40 Position the axis opposite the roller and bend until you obtain the angle measured with the bevel gauge. 2:19 Check the bend with the bevel gauge. 2:37 Place the tube on the marked line and locate the axis for the second bend. 2:48 Place the tube in the bender, with the axis opposite the roller. 2:57 Check for flatness. 3:10 Bend until you obtain the angle measured with the bevel gauge, or until the tubes are parallel. 3:26 Check the height and parallelism of the bayonet fitting. ________________ Links for tools _________________________________ Steel bender: Bevel gauge: https://amzn.to/40wMXbY Measuring tape: https://amzn.to/3GYsqVz ________________ Information ________________________________________
